This dataset includes chemical, discrete sample, physical and profile data collected from R/V Pelagia cruise along the CLIVAR Repeat Section AR07E (EXPOCODE 64PE20070830) in the North Atlantic Ocean from 2007-08-30 to 2007-09-27. These data include dissolved inorganic carbon, total alkalinity, oxygen, silicate, nitrate, phosphate, potential temperature (theta), salinity, and temperature. The instruments used to collect these data include alkalinity titrator, CTD, Coulometer for DIC measurement and bottle. These data were collected by Steven M. A. C. van Heuven of Groningen University and Geert-Jan A. Brummer of Royal Netherlands Institute for Sea Research (NIOZ) as part of the CLIVAR_AR07E_2007 dataset. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

The expedition PS94 Trans-Arctic survey of the Arctic Ocean in transition ("TransArc II") aimed at capturing the physical, biological, and chemical changes of the Arctic Ocean. The retreat of the multi-year sea ice over the last decades, and the changes in ice and ocean circulation are tightly linked to changes in the heat and fresh water distribution with consequences for the gas exchange between ocean and atmosphere, for biogeochemical cycling and for organisms and ecosystems in the sea ice, in the water column and on the sea floor. This dataset includes discrete bottle measurements of Dissolved Inorganic Carbon (DIC), Total Alkalinity, pH on total scale, water temperature and salinity, oxygen, nutrients, CFCs, Dissolved organic carbon and other parameters measured onboard the R/V Polarstern in the central Arctic Ocean during the PS-94, ARK-XXIX/3, TransArc-II cruise (EXPOCODE 06AQ20150817) from 2015-08-17 to 2015-10-15.

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, water temperature, salinity, dissolved oxygen, nutrients, and other measurements collected during the R/V Hans Brattstrøm cruise (EXPOCODE 58HB20201110) in the Norwegian Sea, North Atlantic Ocean from 2020-11-10 to 2021-11-16.

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons (CFC-11, CFC-12, CFC113) and carbon-14/13 during the R/V James Clark Ross cruise JR18002 (EXPOCODE 74JC20181103) along the Global Ocean Ship-Based Hydrographic Investigation Program (GO-SHIP) Section SR01b in the Drake Passage, South Atlantic Ocean, Southern Ocean from 2018-11-03 to 2018-11-23. The International GO-SHIP Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS/CLIVAR hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.
